Abstract
(EN) This laser oscillation device 1 is for a direct-diode laser method in which laser light is output to a laser machining head 3 on the basis of a drive command from a system control device 5 for controlling a laser robot 4 provided with the laser machining head 3. This laser oscillation device 1 comprises: a laser module 10 having, embedded therein, a plurality of laser diodes connected in series or in parallel; a power supply circuit 20 for driving the laser module 10 with a constant current; and a power supply control unit 30 for controlling the power supply circuit 20 on the basis of the drive command and carrying out failure diagnosis on the basis of the region in a diagnosis map, which has been divided into a plurality of regions beforehand, that the current and voltage applied to the laser module 10 fall into.
(FR) L'invention concerne un dispositif d'oscillation laser 1 qui est destiné à un procédé laser à diode directe dans lequel une lumière laser est délivrée à une tête d'usinage laser 3 sur la base d'une commande d'entraînement provenant d'un dispositif de commande de système 5 pour commander un robot laser 4 comprenant la tête d'usinage laser 3. Ce dispositif d'oscillation laser 1 comprend : un module laser 10 ayant, intégré à l'intérieur de celui-ci, une pluralité de diodes laser connectées en série ou en parallèle; un circuit d'alimentation électrique 20 pour commander le module laser 10 avec un courant constant; et une unité de commande d'alimentation électrique 30 pour commander le circuit d'alimentation électrique sur la base de la commande d'entraînement et effectuer un diagnostic de défaillance sur la base de la région dans une carte de diagnostic, qui a été divisée en une pluralité de régions au préalable, de sorte que le courant et la tension appliqués au module laser 10 entrent dans ceux-ci.
